Used to trolling teenagers and buzzed beachgoers, Fox News host Jesse Watters clearly met his match during the Saturday airing of his standalone show “Watters’ World,” as he got trolled hard by an alt-right YouTuber posing as a member of the radical-left “antifa” movement.

The entire five-minute segment is completely cringe-worthy, as the very self-impressed former Bill O’Reilly producer clearly had no idea that he was being taken for a ride by an alt-right troll who calls himself BG Kumbi but who gave the name “Kevin” to Watters’ producers.

There were lots of things that should have tipped Watters and his staff that they were the subjects of a ruse. Had they bothered to do a single Google search, they would have found that the “Boston Antifa” group with which Kumbi claimed to be affiliated is actually a satire website run by racist right-wingers living in Oregon. Literally the third result is an article debunking the fake antifa collective.

A better informed production team would also have realized that antifa activists never do media interviews without wearing some sort of facial covering. The kitchy picture of Karl Marx that Kumbi had behind himself ought to have been another clue as well.

But Watters barreled into the interview with vigor, blissfully ignorant of what was about to happen to him. The most ridiculous moment was Watters’ attempt to challenge Kumbi about an incident that took place in Pennsylvania when an antifa activist stabbed a horse with a flag pole.

“OK, what about when an antifa member stabbed a police horse in the neck with a knife. Was the horse a racist Trump supporter?” Watters asked.

“Yes,” the troll replied, keeping a completely straight face.
